Lung Cancer in Non-Smokers: Symptoms & Risk Factors

Lung cancer is the leading cancer killer in the United States, according to the American Lung Association. However, smokers aren't the only ones who get lung cancer. In fact, 13 percent of lung cancer deaths are non-smokers. Lung cancer in non-smokers can be caused by exposure to secondhand smoke, radon, asbestos and other hazardous materials and chemicals.
